What is it?

From WinLIKE Wiki

WinLIKE is a window manager for web applications and websites and has been written in JavaScript (DHTML). With its help user interfaces can be developed for the Web, which resemble those from window-based operating systems (e.g. Microsoft Windows). Through the use of several windows, reloads within the browsers are reduced, as in Ajax, and it remains up to the user to decide which content is to be shown or closed (also see Multiple Document Interface).

WinLIKE is a technology for web developers and is free of charge for non-commercial use. The program works on all platforms (Windows, Unix, Mac OS etc.) in Mozilla based browsers such as Netscape or Mozilla Firefox as well as under Windows in Internet Explorer. In addition, WinLIKE is compatible with text-based clients such as search engines or Lynx (web browser). Since WinLIKE is a pure browser based technology, it can be used with or even be generated by all common programming languages like PHP, Active Server Pages, ASP.NET, Perl or JSP.

Here is an example of a window definition within an HTML page, where the hyperlink <a href="sample.html" target="win1">linkname</a> loads its content into a window named win1 which can be defined as follows:

<script>
WinLIKE.definewindows=my_defs;
function my_defs()
{
       var x=new WinLIKE.window('Demo',150,90,240,240,1);
       x.Nam='win1';                   // name of the window
       x.Ski='light';                  // window skin/layout
       x.Adr='samples/test.html';      // address of the content
       x.Mn=true;                      // usually minimized
       x.Vis=false;                    // invisible at startup
       WinLIKE.addwindow(x);
}
</script>
